Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals (信号) from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called“galvanometer”. The galvanometer is placed on a leaf of the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them-perhaps by pulling off leaves or by pulling it out of its pot?-then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects(昆虫).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.
1．Most people believe that plants have no feelings because ________.
[ ]
A．they do not move or speak
B．they cannot receive signals from outside
C．this may not be completely true
D．this is unbelievable
2．Backster was surprised at the results of his studies because ________.
[ ]
A．he destroyed an insect
B．he destroyed a plant by pulling off its leaves
C．he found that plants could express feelings of shock
D．he found that plants could move and speak after all
3．The plants sent out signals ________.
[ ]
A．only when Backster started to destroy plants
B．when Backster destroyed plants or other living things
C．only when he destroyed things such as insects
D．only when Backster placed the galvanometer on the leaves of the plants
4．The scientist called Sauvin ________.
[ ]
A．did not agree with Backster's ideas
B．did not get the same sort of results as Backster did
C．got different results from Backster's
D．found out some of the same things that Backster did
5．Which of the following is true according to the passage?
[ ]
A．The electrical charge plants carry may shock or frighten us
B．A tree will signal when it has been cut down
C．Sauvin could make his plants send out signals some distance away
D．Plants have feelings because they can receive signals without moving

Can trees talk? Yes--but not in words. Scientists have reasons to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree（柳树）attacked in the woods by caterpillars（毛毛虫）changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special vapour--a signal causing its neighbours to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn't need to be always in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar（花蜜）for honey. So why shouldn't trees have ways of sending messages?
（1）When attacked, a willow tree will protect itself by _______.
[ ]
A. changing its leaves' chemistry
B. changing its leaves' colour
C. talking to caterpillars
D. sending out a special vapour
（2）From the passage we know that caterpillars _______ .
[ ]
A. like willow trees
B. enjoy eating fallen leaves
C. feed on willow tree leaves
D. could communicate with willow trees
（3）Caterpillars will stop eating willow tree leaves which _______ .
[ ]
A. have a chemical change and become tasteless
B. have a pleasant taste
C. are being attacked
D. are communicating
（4）According to the passage, how do willow trees communicate with each other?
[ ]
A. They talk in words.
B. They send out a special vapour.
C. They wave their leaves.
D. They make special sounds.
（5）According to the passage, bees communicate with each other by ______ .
[ ]
A. talking
B. making unusual sounds
C. singing songs
D. flying in certain patterns

阅读理解：
Computer people talk a lot about the need for other people to become “computer - literate”.But not all experts (专家) agree that this is a good idea.
One pioneer, in particular, who disagrees, is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer, David doesn't see it that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them “people -literate”.
David Tebbutt thinks Computertowns are most successful when tied to a computer club that he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don't have to learn computer terms, but the experts have to explain in plain language. The computers are becoming “people-literate.”
1．Which of the following is David Tebbutt's idea on the relationship between people and computer?
[ ]
A．Computer learning should be made easier.
B．There should be more computer clubs for experts.
C．People should work harder to master computer use.
D．Computers should be made cheaper so that people can afford them.
2．We can infer from the text that “computer- literate” means ________.
[ ]
A．being able to afford a computer
B．being able to write computer programs
C．working with the computer and finding out its value
D．understanding the computer and knowing how to use it
3．The underlined word “it” in the second paragraph refers to the idea that computertowns ________.
[ ]
A．help to set up more computer clubs
B．bring people to learn to use computers
C．bring more experts to work together
D．help to sell computers to the public
4．David started computertown UK with the purpose of ________.
[ ]
